From 2c5e8c52c6354f77c4019357be8231bcc34456f8 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 7 Apr 2015 11:09:54 +0200 Subject: perf tools: Merge all perf_event_attr print functions Currently there's 3 (that I found) different and incomplete implementations of printing perf_event_attr. This is quite silly. Merge the lot. While this patch does not retain the exact form all printing that I found is debug output and thus it should not be critical. Also, I cannot find a single print_event_desc() caller.
